Study on adaptation of low-temperature compensative die stone for alumina-zirconia nano-composite infiltrated ceramic copings

目的研究氧化铝-氧化锆纳米复合渗透陶瓷低温补偿代型材料的适合性。方法在一个标准代型基础上分别制备8个氧化铝-氧化锆纳米复合渗透陶瓷底层冠,粘结后测定低温补偿代型材料的适合性。结果采用低温补偿代型材料制作的氧化铝-氧化锆纳米复合渗透陶瓷表现出良好的适合性,平均绝对边缘间隙量57.42μm,在120μm的临床可接受范围内。结论氧化铝-氧化锆纳米复合渗透陶瓷低温补偿代型材料具有良好的适合性。

Objective To evaluate the accuracy of adaptation of the low temperature compensative die stone for alumina-zirconia nano-composite infiltrated ceramic copings. Methods Alumina-zirconia nano-composite infiltrated ceramic copings were fabricated and their accuracy of adaptation was measured respectively. Results The low-temperature compensative die stone for alumina-zirconia nano-composite infiltrated ceramic copings exhibited high accuracy of adaptation： the mean absolute margin of the base copings was 57.42μm,and in the clinical receiving range of 120μm. Conclusion The adaptation of the low temperature compensative die stone for alumina-zirconia nano composite infiltrated ceramic copings can meet the clinical require.
